Flora of North America species comparison

few to several from base, erect or outer decumbent, 0.5–2.5 dm.

several from base, erect or outer usually decumbent toward base, (from below a terminal tuft of mostly erect leaves, unbranched), 1–2 dm.

blade suborbicular to elliptic or ovate or deltate, 0.5–2(–6.5) cm, margins entire or shallowly dentate.

blade ovate to elliptic, 2–4 cm, (base gradually narrowed to petiole), margins entire, (surfaces densely pubescent with trichome layers).

(proximal shortly petiolate, distal usually sessile);

blade narrowly elliptic or obovate, (0.5–)1–2.5(–4) cm, margins entire.

(remote, proximal shortly petiolate);

blade spatulate to oblanceolate, similar to basal, (base often cuneate), margins entire.

compact, (± subumbellate to densely corymbiform, elongated or not).

elongated.

sepals ± elliptic, 4.5–7(–8.5) mm, (median pair thickened apically);

petals (sometimes white), suborbicular to obovate or obdeltate, 6.5–15 mm, (base narrowing to broad claw, apex sometimes emarginated).

sepals linear-oblong, 5–7 mm, (lateral pair subsaccate);

petals (erect), lingulate, 8–10 mm, (claw barely differentiated from blade).

(usually spreading at right angles, sometimes nearly erect, ± straight), 5–15(–20) mm, (stout).

(recurved), 7–10 mm.

(sessile or shortly stipitate, less than 1 mm), subglobose to broadly ellipsoid, inflated or slightly compressed (terete or subterete), (4–)5–8(–9) mm;

valves (not retaining seeds after dehiscence), glabrous;

replum as wide as or wider than fruit;

ovules 8–16 per ovary;

style 4–8(–9) mm.

(usually pendent, sessile), subglobose, slightly flattened (angustiseptate), 4–5 mm;

valves densely pubescent, trichomes somewhat spreading;

ovules 8–12 per ovary;

style 4–5 mm.

flattened.

plump, (mucilaginous when wetted).
